Stop if

Hold point on vapor barrier on exterior insulation: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't install without vapor barrier in conditioned spaces. Don't use wrong tape type. Don't leave gaps or tears unrepaired.
